Abstract (en)

It is an object of the present invention to ensure higher processing accuracy with a simple mechanism, and simultaneously, efficiently process a groove. A groove processing tool (2) for a thin-film solar cell is held by a holder (17) and configured to be reciprocated relatively to a substrate together with the holder (17) along a prospective scribing line on the substrate for forming a groove on the substrate. The tool (2) includes a tool body (36) held by the holder (17) and a blade end (37) formed on the tip of the tool body (36). The blade end (37) includes a pair of outgoing-side and returning-side cutting edges (38a, 38b) on its tip in reciprocating directions. The blade end (37) further includes a pair of opposed outgoing-side and returning-side lateral faces (37a, 37b). The lateral faces (37a, 37b) are tilted and symmetrically formed for reducing a reciprocating-directional width of the blade end (37) towards the blade end tip.
